The first voice other than Ben or Sam to appear was Ian Miller on Episode 8, co-hosting in Ben's absence (from what I can tell, the only show that Ben missed), creating a Miller vs. Miller dynamic. Woj and I have guest hosted thrice each, along with single guest host appearances by Will Woods, Zachary Levine, and Ian. There were two simulcast episodes with FanGraphs, so I guess Carson Cistulli was a two-time co-host.

We should probably also acknowledge Pete Barrett and Nick Wheatley-Schaller who each produced 30 segments during the season-previews.
